Fighters introduced from 2005 - present are recognized as 5th gen fighters.These aircraft combine high-performance airframes, internally carried advanced air-to-air, and air-to-ground weapons, all aspect stealth, Low Probability of Intercept
Radar (LPIR), and networks for shared situation awareness. Their advanced highly integrated avionics
systems, with on and off-board sensor fusion, free pilots to focus on
the task, rather than the different systems that generate the information.
Only few countries are developing their own fifth gen fighters, but as we know US is the only country that has 5th generation fighters in service.
To make it clear, here's the list of 5th generation fighters:

The Mikoyan LMFS (Light Multi-Role Tactical Aircraft)
is a proposed single engine stealth fighter
aircraft based on the canceled MiG 1.44. It is said to be 30 percent lighter
than the Sukhoi PAK FA. It will use either one Lyulka AL-41 or one Klimov
VK-10 Turbofan.

HAL Advanced Medium Combat Aircraft(AMCA) (India)

Introduction planned on 2018

The Advanced Medium Combat Aircraft has been shaped for low radio
observability. It will carry an internal weapons bay. It would feature supercruise
and thrust vectoring capabilities. Large
amounts of composites and other materials will be used for enhancing
stealth features.
The aircraft will also feature Integrated Modular Avionics and Data
fusion capabilities. Its avionics will be specially designed for
complete situational awareness, pilot decision aid and aircraft
management. It will have advanced sensors and Net-centric warfare
capabilities. The aircraft will be equipped with missiles like DRDO
Astra and other future advanced missiles, stand-off weapons and
precision weapons.
